Nutritional Requirements of Calamondin Trees

Calamondin trees, also known as calamansi or Philippine lime, are small citrus trees that produce small, round fruits resembling tangerines. To ensure healthy growth and optimal fruit production, it is important to meet the nutritional requirements of these trees.

Macronutrients

Nitrogen (N): Nitrogen is essential for the overall growth and development of calamondin trees. It promotes leaf and stem growth, as well as the production of chlorophyll. Adequate nitrogen levels can be maintained by applying a balanced fertilizer with a higher nitrogen content during the growing season.

Phosphorus (P): Phosphorus is crucial for root development, flowering, and fruit production. It aids in energy transfer and promotes overall plant vigor. A fertilizer with a higher phosphorus content should be applied during the early stages of growth and when the tree is flowering.

Potassium (K): Potassium is important for the overall health and disease resistance of calamondin trees. It helps regulate water movement within the plant and enhances fruit quality. Fertilizers with a higher potassium content should be applied during fruit development and maturation.

Micronutrients

Iron (Fe): Iron is essential for chlorophyll production and overall plant growth. Calamondin trees may exhibit yellowing of leaves (chlorosis) if there is an iron deficiency. Iron chelate or iron sulfate can be applied to the soil to correct this deficiency.

Zinc (Zn): Zinc is necessary for various enzymatic reactions within the plant. It plays a vital role in the synthesis of growth hormones and the formation of chlorophyll. Zinc deficiencies can be corrected by applying zinc sulfate to the soil.

Manganese (Mn): Manganese is involved in photosynthesis, nitrogen metabolism, and enzyme activation. A deficiency in manganese can lead to stunted growth and reduced fruit production. Manganese sulfate can be applied to the soil to address this deficiency.

Boron (B): Boron is essential for cell wall formation, pollen germination, and fruit development. It also aids in the uptake of other nutrients. Boron deficiencies can be corrected by applying borax or boric acid to the soil.

Copper (Cu): Copper is necessary for various enzymatic reactions and plays a role in carbohydrate metabolism. A deficiency in copper can result in wilting and dieback of shoots. Copper sulfate can be applied to the soil to address this deficiency.

Molybdenum (Mo): Molybdenum is required for nitrogen fixation and enzyme activity. It is essential for the conversion of nitrate to ammonia within the plant. Molybdenum deficiencies can be corrected by applying sodium molybdate to the soil.
